Question 1

What is OwnSender?

Accepted Answer

OwnSender is a tool for sending personalized communication at scale. You build a reusable template, connect a spreadsheet of recipients, and OwnSender produces an individual message for each person — along with an individual document to attach, if the send needs one. The workflow is create, personalize, automate, send, track. It is designed for sends where the content genuinely differs per recipient, rather than one identical message going to a list.

Question 2

What do I need to get started?

Accepted Answer

Two things: a template, and recipient data. The template holds your email content and, optionally, the design of a document to generate. The data is a CSV, Excel or JSON file with one row per recipient. To actually send, you also connect your own sending account — Gmail, Outlook, or any SMTP service you already use.

Question 3

Do I need to be technical to use it?

Accepted Answer

No. Building a template and mapping spreadsheet columns to variables is done through the interface, with no code involved. There is also a REST API and webhooks for teams who want to drive generation and sending programmatically, available on plans that include API access.

Question 4

Can I reuse a template?

Accepted Answer

Yes — reuse is the point of a template. The same template can be sent again with completely different recipient data, so the second campaign costs a fraction of the effort of the first. Templates are versioned, so editing one does not silently change what an already-completed campaign was built from.

Question 5

Can I use variables inside templates?

Accepted Answer

Yes. Wrap a name in double braces — for example {{full_name}} — and it becomes a variable. Variables work in the subject line, in the email body, and inside the design of a generated document. When a campaign runs, each variable is replaced with that recipient's value from your dataset.

Question 6

What file formats can OwnSender generate?

Accepted Answer

Generated files can be PDF, PNG, JPG, WebP or SVG. PDF is the usual choice for a document meant to be read or printed, such as a certificate or an invoice. Those five are the formats the generation engine supports. Anything not on that list is not available.

Question 7

How does personalization work?

Accepted Answer

You put variables in your template where the content should change, then map each variable to a column in your dataset. When the campaign runs, OwnSender reads each row and produces one message — and one document, if configured — with that row's values filled in. Nothing is edited by hand. A thousand recipients means a thousand individually rendered messages from one template.

Question 8

Can I personalize attachments?

Accepted Answer

Yes, and this is one of the main things that distinguishes OwnSender from ordinary bulk email. The same variables that personalize the email text also personalize the document design, so each recipient receives a file built specifically for them — their name, their reference number, their amounts. The generated file is attached to that recipient's email automatically.

Question 9

Can I preview a personalized message before sending?

Accepted Answer

Yes. You can preview how a template resolves against real rows from your dataset, so you can confirm the variables are mapped to the columns you intended before anything is sent.

Question 10

What happens if a row is missing a value?

Accepted Answer

Rows that cannot be sent as prepared are marked Blocked rather than sent with a gap in them. Blocked means nothing was attempted and the fix is yours — correct the address, fill in the missing field, then prepare the campaign again. This is deliberately separate from Failed, which means a send was attempted and the mail provider rejected it.

Question 11

Can I upload CSV or Excel data?

Accepted Answer

Yes. Datasets can be uploaded as CSV, Excel (.xlsx or .xls), or JSON. OwnSender reads the header row and makes every column available as a variable. Rows can also be supplied through the API, or typed in by hand for a small send.

Question 12

Do I have to rename my spreadsheet columns?

Accepted Answer

No. You map columns to template variables, so your file keeps whatever headings it already has. A column called document_number can feed a variable called {{reference_number}} without editing the file. Mapping is saved per template, which means one dataset can drive several different campaigns.

Question 13

Can I reuse a dataset across campaigns?

Accepted Answer

Yes. Uploaded datasets are saved and stay available for future sends, with their own variable mapping per template.

Question 14

Which email providers can I connect?

Accepted Answer

Gmail, Outlook, or any service you can reach over SMTP. Outlook covers both a personal outlook.com or hotmail account and a work or school Microsoft 365 mailbox. The SMTP option covers everything else that gives you a host, port, username and password — Zoho, Amazon SES, SendGrid, Mailgun, a cPanel mailbox, or your own mail server. Messages go out from your own connected account, not from a shared OwnSender address, so replies come back to you.

Question 15

Can I select specific recipients?

Accepted Answer

Yes. By default a campaign includes every row in the dataset, and you can instead choose an explicit subset of rows to send to. You can also take individual recipients out of a prepared campaign without affecting anyone else, and put them back again later.

Question 16

Can I send emails in batches?

Accepted Answer

Yes. You can send in chunks of a size you choose — from 1 up to 10,000 recipients per chunk — with a wait between chunks measured in seconds, minutes or hours, up to 24 hours. This lets a large campaign go out at a deliberate pace instead of all at once, and it continues on its own between chunks.

Question 17

Can I add a delay between emails?

Accepted Answer

Yes. You can set a gap between individual messages, either a fixed interval or a randomised one within a range you define. The per-message gap can be up to five minutes. For longer waits, chunking is the better tool — it pauses the send properly rather than holding a pass open.

Question 18

Is there a limit on how many emails I can send?

Accepted Answer

OwnSender does not itself cap the number of emails. What your plan includes is a monthly allowance of generated files, and each personalized document you produce counts toward it. The practical ceiling on sending is whatever your own connected email provider allows — Gmail, Microsoft and SMTP services each apply their own limits, and those are between you and them.

Question 19

Can I schedule a send for a specific time?

Accepted Answer

Not to a clock time — a campaign starts when you send it, rather than at a date and time you set in advance. What you can do is control the pace once it starts, and that covers most of what scheduling is usually for: send in chunks of a size you choose, wait anywhere from a second to 24 hours between chunks, and set a gap between individual messages. You can also dispatch a fixed number now and continue later. A campaign runs on its own once started, so a large send spread over hours needs no supervision.

Question 20

Can I stop an active sending plan?

Accepted Answer

Yes. Pausing stops a running campaign while keeping it intact: every recipient still waiting stays pending, and pressing send again continues from exactly where it stopped. A message already in flight is always finished — the send never stops mid-message. Cancelling ends the campaign instead. In both cases, emails that have already gone out cannot be recalled.

Question 21

Can I cancel a campaign before it starts?

Accepted Answer

Yes. A campaign that has been prepared but not yet started can be cancelled outright, and nothing will be sent.

Question 22

Can I retry recipients that failed?

Accepted Answer

Yes. A campaign can retry just the recipients whose sends failed, without re-sending to anyone who already received their message. Recipients marked Blocked are a different case: nothing was attempted for them, so the fix is to correct the underlying data and prepare the campaign again.

Question 23

How is email delivery tracked?

Accepted Answer

Every recipient in a campaign carries its own status, so a problem affecting a handful of rows never hides behind a thousand successful ones. The statuses are Pending, Sending, Sent, Blocked, Failed and Cancelled. Sent means the receiving mail server accepted the message. Failed means it was attempted and the provider rejected it, with the provider's reason recorded.

Question 24

What happens when an email bounces?

Accepted Answer

OwnSender does not track bounces, and it is worth being precise about why rather than implying otherwise. When a mail server accepts a message it takes responsibility for it, and that is the point at which OwnSender records the recipient as Sent. The receiving server can still bounce the message, file it as spam, or drop it silently minutes later — none of which is reported back to the sending API. So a bounce shows up in the inbox of the account you connected, as a bounce notification from your provider, not in OwnSender's campaign view. Sent is an accurate record of a successful handover, not a claim about delivery.

Question 25

Does OwnSender track opens and clicks?

Accepted Answer

No. Open and click tracking are not part of the product, and the campaign view does not report them.

Question 26

How does billing work?

Accepted Answer

You choose a plan and a billing period — monthly or yearly — and pay for that period up front. Yearly is priced at ten months for twelve, which works out about 17% cheaper than paying monthly. Prices are shown in Indian rupees (INR).

Question 27

Can I change plans?

Accepted Answer

Yes, in both directions. Moving up to a larger plan takes effect immediately. Moving down is booked rather than applied straight away: the period you have already paid for is honoured to the day, and the smaller plan takes over when it ends.

Question 28

What happens if I reach my monthly allowance?

Accepted Answer

The action that would exceed it is refused and OwnSender tells you which limit you reached. Nothing runs past your allowance, and there is no overage charge. The generated-files allowance resets at the start of each billing period. Ongoing limits like templates and team members free up when you remove something or move to a larger plan.

Question 29

Is there a free plan?

Accepted Answer

Yes. The Free tier is what every new account starts on, and it is intended for evaluating the product properly rather than as a demo.
